Question

Windows XP shutdown.

I recently fixed a pc and after three weeks the computer shutdown by itself. I turn on the computer and after Windows XP load completely, the pc shutdown several times. I checked the power supply, the heat-sink fan, memory RAM and the capacitors. What It could be going on?

How did you check the power supply?

If you didn't plug it into a PS Tester you haven't checked it properly.

Secondly what Temp is the system set to to restart the unit? This is a BIOS Setting and needs to be high enough to prevent the unit constantly restarting when the CPU starts to get warm.

If the unit is just restarting after it is turned on it sounds like a Hardware problem not a software issue so to prove or disprove this try a Live Linux and see if it keeps running or not. It it does you need to look at a Software problem but if it keeps restarting you have a Hardware issue.

First thing to check would be over heating somewhere...

check for poor ventilation, maybe add another fan. Also, check the voltage output of the power supply, it may not be providing sufficient power. Are you getting any type of error message? Might restart in debug mode and check for trouble spots. Is the hard drive failing? Might run a few tests on the hard drive. If I think of something else, I'll add a reply...you did check the RAM and all additional peripherals (video adapter, NIC, etc.)?
